Atacama Desert: On the trail of fog trapping and the air plant.
Long-term use of Thies CLIMA weather stations under extreme climatic conditions.
For more than 8 years, several Thies CLIMA weather stations have been operated in the Atacama Desert as part of a German-Chilean research project to investigate fog as a potential sustainable source of water. The region in northern Chile is characterized on the one hand by extremely low precipitation with an average of less than 1 mm of rain per year and sometimes high wind speeds in combination with salty air. On the other hand, there is often high humidity due to rising air masses from the Pacific Ocean within sight, which leads to regular coastal fog (Camanchaca), especially at night. Due to the proximity to the sea, there are salt particles in the air, which place high demands on the corrosion resistance of the measurement technology. UV radiation is extremely high and temperatures fluctuate between over 35°C and just above freezing, depending on the time of year and time of day. The investigation of local vegetation as a bioindicator for fog availability requires extremely robust and at the same time precise meteorological measurement technology. The overall technical solutions must be flexibly adaptable in order to be able to integrate additional sensor technology for new scientific questions.
In this environment, Thies CLIMA weather stations have proven themselves many times and over many years. In detail, the following are used:
1) Wind speed and wind direction: Compact series https://wmo.int/
